2000 Firebird gauges and lights out

My gf has a firebird and shes claiming her gauges, radio, and dashlights are not working. I haven't taken a look at it yet and won't have time until tomorrow. Her dad checked fuses and they're all good. I'm sure its something minor but just wondering if anyone has experienced this issue?

I'm thinking he may have overlooked a fuse.

Any help appreciated

Thanks!
